What kind of network is this? It's surely not mainnet or any of the public testnets.

[phpmac]

My own private chain network has modified the chainid. 2024 年 5 月 28 日星期二 19:21, Sina M ***@***.***(mailto:2024 年 5 月 28 日星期二 19:21, Sina M <<a href=)> 来信：

Ok it sounds like you have also modified the geth source?

The version must be outdated too. Geth doesn't support PoW mining anymore.

[phpmac]

Yes, I'm using the old version. It's a private chain. How to solve this problem? The block speed is also extremely fast. The disk is quickly occupied, and multiple nodes can't catch up synchronously. Do you know how to solve it? 2024 年 5 月 29 日星期三 03:05, Sina M ***@***.***(mailto:2024 年 5 月 29 日星期三 03:05, Sina M <<a href=)> 来信：
